Abstract: A navigation system for a marine vessel incudes one or more proximity sensors, each at a sensor location on the marine vessel and configured to measure proximity of objects in an area surrounding the marine vessel and generate proximity measurements, and a control system configured to receive the proximity measurements measured by the one or more proximity sensors. From the received proximity measurements, four linearly-closest proximity measurements to the marine vessel are identified, including one closest proximity measurement to the marine vessel in each of a positive X direction, a negative X direction, a positive Y direction, and a negative Y direction. A most important object (MIO) dataset is generated identifying the four linearly-closest proximity measurements and propulsion of the marine vessel is controlled based at least in part on the MIO dataset.

Abstract: A propulsion control system on a marine vessel includes at least one propulsion device configured to propel the marine vessel and at least one proximity sensor system configured to generate proximity measurements describing proximity of objects surrounding the marine vessel. A control system is configured to receive the proximity measurements, access a preset buffer distance surrounding the marine vessel, calculate a velocity limit for the marine vessel in one or more directions of the objects based on a difference between the proximity measurements and the preset buffer distance surrounding the marine vessel so as to progressively decrease the velocity limit as the marine vessel approaches the preset buffer distance from any of the objects, and control the at least one propulsion device such that a velocity of the marine vessel does not exceed the velocity limit in the direction of any of the objects.

Abstract: A method of controlling a propulsion system on a marine vessel includes receiving proximity measurements describing locations of one or more objects with respect to the marine vessel, receiving a command vector instructing magnitude and direction for propulsion of the marine vessel with respect to a point of navigation for the marine vessel, and then determining a funnel boundary based on the command vector. When an object is determined to be within the funnel boundary, a propulsion adjustment command is calculated to move the marine vessel such that the object is no longer in the funnel boundary. At least one propulsion device is then controlled based on the propulsion adjustment command.

Abstract: A method for controlling propulsion of a marine vessel powered by a marine propulsion system including a plurality of propulsion devices includes operating at least one proximity sensor to determine a relative position of the marine vessel with respect to an object, the at least one proximity sensor having a field of view (FOV), identifying a trigger condition for expanding the FOV of the at least one proximity sensor, and determining whether the object will be sufficiently captured based on recent vessel angle data of the marine vessel. Upon determining that the object will not be sufficiently captured, thrust and/or steering position of at least one of the plurality of propulsion devices is controlled to expand the FOV of the at least one proximity sensor by inducing a roll movement or a pitch movement of the marine vessel.

Abstract: A marine propulsion control system includes at least one propulsion device, an input device enabling user control input commanding movement direction and velocity, and at least one proximity sensor configured to generate proximity measurements describing a proximity of surrounding objects. A controller is configured to first limit the velocity commandable by the user via the input device based on the proximity measurements so as to maintain the marine vessel at least a buffer distance from any of the objects, then receive a user-generated instruction to suspend maintenance of the buffer distance in at least one direction and a user control input via the input device to move the marine vessel in the at least one direction and toward a first object. The at least one propulsion device is then controlled based on the user control input such that the marine vessel approaches and impacts the first object.

Abstract: A method for controlling low-speed propulsion of a marine vessel powered by a marine propulsion system having a plurality of propulsion devices includes receiving a signal indicating a position of a manually operable input device movable to indicate desired vessel movement within three degrees of freedom, and associating the position of the manually operable input device with a desired inertial velocity of the marine vessel. A steering position command and an engine command are then determined for each of the plurality of propulsion devices based on the desired inertial velocity and the propulsion system is controlled accordingly. An actual velocity of the marine vessel is measured and a difference between the desired inertial velocity and the actual velocity is determined, where the difference is used as feedback in subsequent steering position command and engine command determinations.

Abstract: A method of controlling propulsion of a marine vessel includes receiving proximity measurements from one or more proximity sensors on the marine vessel and limiting user input authority over propulsion output in a direction of an object by at least one propulsion device based on the proximity measurement so as to maintain the marine vessel at least a buffer distance from the object. The method further includes suspending maintenance of the buffer distance from the object in response to a user-generated instruction. Then, when user control input is received via a user input device to move the marine vessel in the direction of the object, the at least one propulsion device is controlled based on the user control input such that the marine vessel approaches and impacts the object.

Abstract: A method of controlling a propulsion system on a marine vessel includes receiving proximity measurements describing locations of one or more objects with respect to the marine vessel, receiving a command vector instructing magnitude and direction for propulsion of the marine vessel with respect to a point of navigation for the marine vessel, and then determining a funnel boundary based on the command vector. An object is identified based on the proximity measurements and determined to be within the funnel boundary, and then a propulsion adjustment command is calculated based on the command vector and an angle of the object with respect to the point of navigation. At least one propulsion device is then controlled based on the propulsion adjustment command in order to avoid the object.

Abstract: A method of detecting a collision of the marine vessel includes sensing using distance sensors to determine whether an object is within a predefined distance of a marine vessel, and determining a direction of the object with respect to the marine vessel. The method further includes receiving a propulsion control input at a propulsion control input device, and determining whether execution of the propulsion control input will result in any portion of the marine vessel moving toward the object. A collision warning is then generated.
